ANIMAL PRODUCTION. 477 



Stoffwechsels, n. sen, 6 (1911), No. 139, i//0).— This deals with the chemical 

 composition and the use of the soy bean and its by-products for feeding pur- 

 poses. 



The investigations of others on this subject are reviewed, and digestion ex- 

 periments by the author are reported in which the coefficients of digestion in 

 exijeriments with wethers were as follows : Soy-bean cake from which the oil 

 had been removed by pressure, protein 92.8. fat 92.8, nitrogen-free extract 102.7, 

 fiber 36.1 per cent ; cake from which the oil had been extracted, protein 91.9, 

 fat 67.6, nitrogen-free extract 105.4, fiber 99.3 per cent. Averaging these results 

 with those obtained by other investigators it is estimated that in 100 lbs. of 

 pressed soy-bean cake there are the following amounts of digestible nutrients: 

 Protein 43.3, nitrogen 31.1, fat 6.9, fiber 4.4 lbs. ; in the extracted cake, protein 

 48, nitrogen-free extract 34.6. fat 1.2, fiber 5.2 lbs. 



A bib]iograi)hy of the literature on the subject is appended. 



Molasses and sugar foods for live stock, W. Goodwin (Jour. Pd. Agr. 

 [Lcmdon], 18 {1911), No. 2, pp. 97-106.). — A summary of information on the 

 "salue of molasses as a feed for live stock, based on the latest scientific investi- 

 gations in different countries. The author warns stock feeders against paying 

 a high price for molasses feeds when the absorbent material is peat or some 

 other substance containing little or no nutritive material. 



On oat-mill refuse feeds, N. Hansson (K. Landtbr. Akad. Handl. och 

 Tidskr., 50 {1911), No. 1, pp. 80-83). — Analyses of the various oat refui^e feeds 

 are given and their feeding value discussed. Attention is called to the varying 

 composition of these feeds and to the necessity of obtaining guaranties for their 

 maximum fiber contents, as well as for the minimum percentages of protein, 

 fat, and carbohydrates which they contain. 



Some condimental stock feeds (kraft-och, halsofoder), their composition 

 and feeding value, X. Hansson {Mcddel. Centralanst. Forsoksv. Jordbruk- 

 somn'idct, 1911, No. Ifl, pp. 16,). — The results of chemical and microscopical ex- 

 .iminations of proprietary stock feeds and one sample of concentrated feeding 

 phosphate are given. Farmers are warned against purchasing feeding stuffs 

 composed of unknown mixtures and sold at high prices under fancy names on 

 account of their medicinal qualities. "Above all it is in order to suspect all 

 preparations sold at much higher prices than our best concentrated feeding 

 stuffs. There are no mixed feeds that can have an appreciably higher value 

 than these for healthy animals." 



Report of commercial feed stuffs, J. E. Halligan {Louisiana Stas. Feed 

 Stuffs lipt. 1909-10, pp. 120). — Analyses are reported of 9,381 samples of cotton- 

 seed meal, cottonseed feed, corn chops, hominy feeds, brewers' grains, poultry 

 feeds, alfalfa meal, molasses and other mixed feeds, and wheat, rice, and animal 

 by-products. 



Notice of judgment {U. S. Dept. Agr., Notice of Judgment 868, pp. 2). — 

 This relates to the misbranding of proprietary feeds. 



Public abattoirs: Their planning and the organization of their personnel, 

 S. M. DoDDiNGTON) JoKi: Meat and Milk Hijg.. 1 (1911), No. .5, pp. 266-21 h).— 

 A consideration of the essential factors which should govern the construction, 

 equipment, and arrangement of public abattoirs. 



Some modern abattoirs and abattoir methods, A. Teimble {Jour. Meat and 

 Milk Hyg., 1 {1911), Nos. 2, pp. 98-109; J,, pp. 207-219, figs. -?2).— These articles 

 contain the main facts of a report of a committee from Belfast, Ireland, which 

 investigated the arrangement and equipment of slaughterhouses and methods 

 of slaughtering as practiced in Rotterdam, Hamburg, Berlin, Dresden, Cologne, 

 and Islington.
